While Friendship can be earned with all of Mistria's residents, Romance is only possible with villagers who are marked as "single" in their Social tab page. As friendships deepen, Dating, and eventually Marriage will be possible with the romance candidates.
Romance
Since v0.14.0 Fields of Mistria has had both "Romantic and Best Friend routes" available for the below candidates.
Basic Mechanics
While the exact mechanics surrounding Marriage are currently (as of 0.15.3) unknown, it has been confirmed that The Player is only able to marry one candidate at a time, and that there will be some kind of "Wedding Event" (though the details have not been announced).
It is unknown if there will be a divorce mechanic.
After marriage, The Player will unlock 3 pieces of their spouse's furniture to decorate their shared house.
